From 6a2e26b95f046a2973a95119910cbe2554c92b46 Mon Sep 17 00:00:00 2001 From: Sughosh Ganu Date: Mon, 12 Apr 2021 20:35:23 +0530 Subject: [PATCH] efi_loader: capsule: Remove the check for capsule_authentication_enabled environment variable The current capsule authentication code checks if the environment variable capsule_authentication_enabled is set, for authenticating the capsule. This is in addition to the check for the config symbol CONFIG_EFI_CAPSULE_AUTHENTICATE. Remove the check for the environment variable. The capsule will now be authenticated if the config symbol is set.
